IMPROVEMENTIN oORN-PLANTEES.

Specification forming part of Letters Patent No. 32,091, dated April 16, 186,1.

To all whom it .may concern:

Be it knownl ``that we, JOSEPH STONE and county of Louisa and State ot' Iowa, have in` vented a new and Improved Combined Corn Planter and Oultivator; and we do hereby declareythat the following is a full, clear, and exact description ot' the same, reference being had to the annexed drawings, making a part f this specication, in which Figure l is a side sectional view ot' our invention, taken in the line m a', Fig. 2. Fig. 2 is a plan or top view of the same. Fig. 3 is a detached longitudinalv section of one of the hoppers, taken in the line y y, Fig. 2.

Similar letters of reference indicate corresponding parts in the several gures.

This invention relates to a novel vand iinproved arran gement ot' parts, as hereinafter fully shown and described, whereby the driver or operator has complete control over the machine, the furrow-shares being allowed to be raised temporarily at the will ofthe driver or operator, and the whole framing ofthe machine also allowed to be raised bodily when required. Provision is also made to insure the proper distribution ot' the seed and the ready adjustment of the shares.

To enable those skilled in the art to fully nnderstand and construct our invention, we will proceed to describe it.

A represents a rectangular frame, which is mounted on two wheels, B B, the axle C of which is bent in crank form, as shown clearly in Fig. 2, and is fitted loosely in bearings a a on the frame A: The wheels B B are placed loosely on the outer ends of the crank parts ofthe axle, and on the axle there is secured a toothed wheel, b, with which a pawl, c, attached to frame A, engages. l

At the back ,part of the frame A there are two uprights, d d, one at each side, which support a drivers s seat, D, and to the axle C there are attached, by two eyes, e e, two curved bars, E E, the upper ends of which are connected by a bar, F. The bars E E are allowed to eyes e e, said pins passing through a bar, g,

in order to admit of the bars E E being ad-h justed nearer together or farther apart, as may be desired.

To the lower end of each bar E a plow, G, is attached, and to eachbar E, just below its connection with the axle C, there is attached wby a bolt a bar, H. The front ends of these bars pass through loops or guides t lt at the front part of the frame A, and have pins t' passing through them in frontof the loops or curved and is in contact with the ground at a point back of the axle, as shown clearly in Fig. On the axle G there is also` placed loosely'a treadle, J, the back end of which is connected by a rod, 7c, to the upper end of an arm, Z, which is attached to a shaft, K, onthe front part ot' the frame A. The shaft K is allowed to tnrnfreely in its bearings m, and at its outerends there are cranks a a, to which the upper ends of curved cutters L L are attached. The lower ends of the cutters L L are connected to furrow-shares M M, and the furrow-shares are secured to `the lower ends ofV tubes N N, which serve to convey seed from hoppers O O to the furrows made by the shares M M. VThe hoppers 0 are attached lto the ends of a bar, l?, which is secured at its back edge tothe frame Aby joints o.

To the under side of the bar Pthere is secured a slide-bar, Q, which extends through the bottoms yof the hoppers O O andis allowed to slide freely back and forth. The sllide-bar Q is perforated with two holes,pp,at each end, and within each hopper O, atabout itscenter, there is placed a cross-plate, g, which has an india-rubber strip, r, attached to its under Y side, the indiarubber strips being on the npper surface ot' the slide-bar and serving as an elfectual cut-oft There are `also placed in each hopper O two cross-rods, s s,one at each side of the plate g and at equal distances from it, as shown clearly in Fig. 3.

To the side bar, Q, there is attached a lever, B, which extends up through the bar P',and is connected by a fnlcrum-pin, t, to an upright, n, on said bar. 4

To one side of the frame A there is attached auadjnstablestep,v,fortheaxle0. (SeeFig.1.)

with seed.

The operation of the machine is as follows: As the m-achine'is drawn along, an operator vibrates the lever R, and consequently the slidebar Q, and the corn is distributed yfrom the hoppers O O by the apertures p. The indiarubber strips r, at the bottoms ot' the plates g, form efcient cut-offs, and at the same time effectually prevent the cutting or bruising of the seed as the lled'apertures p pass under them, while the rods s serve to insure the filling of the apertues p, smoothing oft the tops of the apertures as the latter pass under them and allowingwacant spaces in the apertures to till The shares M and cutters L may he elevated at any time to clear obstructions or when the machine is turning at the ends Qt' rows by the driver depressing With his foot the front end of treadle J, the shares M being thrown forward and upward in a curve by..

means ofthe crankshaft K, the barP, to which the hoppersO areattached, permitting, in consequence ot' the joints b, such movement.

rangement the shares M G are elevated above the surfacel of the ground, the frame A being retained in an elevated state' by the pawl c and wheel b.

The shares -or plo`ws G may be shifted or' turned. laterally', as occasion may require, to cultivate the soil between the furrows made by the shares M M, and the inclination of the shares G, by adjusting the pins t', may be regulated as required, as previously stated.

We do not claim the reciprocity seed-slide Q, perforated near its ends Within the hoppers 0, for that has been previously used; neither do We claimlcentral shares or plows, G, irrespective of the arrangement herein shown and described; but

We do claim as new and desire to secure by Letters Patent;

1. The arrangement of the adjusting-cutters L with the hinged seed-boxes O, oscillating seed-tubes N, and lever J, substantiallyas and for the purposes herein shown and described.

2. The arrangemenbof the double crankaxle with the frame A and spur I, substantially as and for the purposes herein shown and described.

3. Thearrangementof the adjusting-bars H H with the adjustable standardbars E E and frame A, in the manner and for the purpose herein shown and described.
